Upgrade to 2021_02 broke Cloud Identity LDAP
I upgraded my XG-1537 to 2021_02 over the weekend, to get the wireguard support, and after the device rebooted, I had to drop back to a locally authenticated user as Cloud Identity LDAP no longer binds (that's about all I get from the logs "openvpn.auth-user.php: ERROR! Could not bind to LDAP server Gsuite. Please check the bind credentials."
The bind credentials worked perfectly up until the update, as soon as the firewall came back up, I started getting AUTH_FAILED errors from OpenVPN, and have reconfirmed that the configuration is correct, I generated new bind credentials, ensured that the certificate is valid, all without any change in the behavior of the Auth Server.
I can't get much else from the logs currently, I would be happy to dig in deeper, but most of what I'm seeing seems to indicate it's something changed on the pfsense side, as other services using CI LDAP are still working perfectly.
